广州市南洲水厂原水输水管珠江后航道过河管的设计技术

为适应广州市经济建设的发展,进一步缓解广州市水质性缺水的紧张局面,广州市自来水公司经多年论证,最后决定安装两条DN2200原水管从顺德西海取水,横跨顺德、番禺、广州三个行政区,将原水输入南洲水厂,全长约25.6km(以单管段计算)。该工程规模大,涉及面广,在设计及施工过程中需克服的困难多。其中原水管穿越珠江后航道便是众多难题中的代表者。

湖南省雷暴地闪特征初步分析

利用湖南省1980-2010年雷暴日数据、2008-2013年闪电数据,分析了湖南省雷暴和闪电变化特征。结果表明:湖南省属于雷暴多发区,年平均雷暴日数分布呈南高北低的趋势,沿雪峰山有个相对高值区,平均雷暴日数在30d到70d之间。湖南省6年的年平均闪电条数35万余条,雷电高发时段为4-9月,其中7月是全年闪电活动最密集的月份。春季(3-5月)闪电逐时分布呈现双峰型,高峰值出现在02时、17时,夏季(6-8月)闪电多集中在下午15-17时,秋季(9月)高峰期集中在15-16时。湖南省闪电密度分布和闪电强度分布,高值区均在娄底、郴州,全省闪电主要强度分布在20-80kA。     

The Geography of Innovation in China and India

The BRICS countries in general, and China and India in particular, are now widely regarded as the areas of the world likely to challenge the economic leadership of the United States (US) and the European Union (EU). A large part of this challenge will come from rapid technological catch‐up by China and India. Yet, despite a recent rise in interest, there is limited knowledge about how and where innovation takes place in these two leading emerging countries and to what extent the Chinese and Indian territorial systems of innovation differ from those in the EU or the US. In this article we explore the geography of innovation in China and India, concentrating on understanding key territorial‐level innovation trends by country, region and technology field, using the US and the EU as benchmarks. We find significant contrasts between the geography of innovation in China and India and that of the US and the EU. First, the degree of concentration of innovative activities in both countries is extremely high. Levels of agglomeration of innovation in the coastal provinces of China, as well as in Delhi and the South of India, significantly exceed the levels of agglomeration found in the USA and the EU. Secondly, China has witnessed a more rapid increase in the degree of concentration of innovation than India. We posit that the differences in the geography of innovation between, on the one hand, China and India and, on the other hand, between these countries and the developed world are rooted in different institutional settings, different systems of innovation and different national innovation strategies.     

Measuring a boom and bust: The Sydney housing market 2001–2006

The Sydney housing market peaked in 2003. The period 2001–2006 is, therefore, of particular interest since it captures a boom and bust in the housing market. We compute hedonic, repeat-sales and median price indexes for five regions in Sydney over this period. While the three approaches are in broad agreement regarding the timing of the turning point in the housing market, some important differences also emerge. In particular, we find evidence of sample selection bias in our hedonic and repeat-sales data sets (with the former focusing more on better quality dwellings and the latter more on lower quality dwellings). These sample selection biases could in turn cause bias (in opposite directions) in our hedonic and repeat-sales indexes. Median indexes may likewise be biased as a result of an apparent decline in the average quality of dwellings sold in the latter part of the sample. We also find evidence of convergence in prices across regions during the boom and divergence in the subsequent bust.     

Women’s experiences of legitimacy,satisfaction and commitment as entrepreneurs: embedded in gender hierarchy and networks in private and business spheres

ABSTRACT

When a woman perceives legitimacy in her job as an entrepreneur from networks that are often influenced by the gender hierarchy that grants men higher status than women, she is encouraged in her job. What are the effects of gender hierarchy and networks on the legitimacy a female entrepreneur perceives and on her satisfaction and commitment to the job? A sample of 5997 female entrepreneurs in the developing world was surveyed for Global Entrepreneurship Monitor. They were found to experience legitimacy as entrepreneurs in their networks in the private sphere and the business sphere. Gender hierarchy constrains legitimacy more in the private sphere than it does in the business sphere. Legitimacy in the business sphere can fulfil the need to feel competent and enhance job satisfaction, while legitimacy in the private sphere can fulfil the need to feel related and enhance job commitment. The account contributes to a two-level contextualization of experiences: micro-level embedding in networks that are nested in macro-level embedding in gender hierarchy.

Community leadership cycles and the consolidation of neighbourhood coalitions in the new local governance

The success of the new patterns of local governance depends on engaging communities in a range of partnerships at various geographic scales and administrative levels. In practice, this usually falls to a handful of community leaders in any given locality. Our research on area regeneration partnerships in the UK reveals a community leadership cycle, which proceeds through five phases. The first phase consists of the emergence of a first generation of leaders early on in a partnership, in the second phase their position in the partnership is consolidated and loyalty to the partnership developed, followed by a third phase of the cultivation of a second generation of leaders. Then comes a fourth phase in which the new generation of leaders raise their voices to challenge the established patterns of representation in the partnership. In the final phase, individual leaders exit from the partnership. This community leadership cycle is part of building multi-sector leadership coalitions in the neighbourhoods through strategies combining loyalty, voice and exit.     

Trade Openness and Spatial Inequality in Emerging Countries

Abstract

Emerging world countries have experienced over the last two decades a significant change in their trade patterns. Bold trade reforms have been followed by rapid rises in international trade levels. However, despite these radical changes, we know remarkably little about how changes in trade patterns are affecting the evolution of regional inequality in the developing world. This paper addresses the link between trade openness and spatial inequality across 22 emerging countries over the period between 1990 and 2006. Our findings show that changes in international trade bring about a significant rise in within-country inequality across the developing world and that this impact is greatest in the poorest countries. This result is robust to the inclusion of a number of control variables, and to changes in the specification of the sample and in the measure used to quantify the level of regional disparities. Consequently, the increase in trade exposure across the emerging world, while possibly benefiting the countries involved in the process in aggregate terms, is generating winning and losing regions.
